STEAM-EN GIN E LUBRICA'IOR.

Application filed April 30, 1923. Serial No. 635,706.

To all whom 2'2. may concern:

Be it known that we, EDGAR A. SMITH and NORMAN United States,

H. MOORE, citizens of the residing at Wichita Falls, in

the county of Wichita and State of Texas,

have invented a new and useful Steam-Engine Lubricator, of which the following is a specification. The lnventi steam engine tirely automatically,

ing and decre englne.

on relates to an automatic lubricator that operates en the flow of oil increasasing with the speed of the A further object of the invention 'is to provide a device of this nature that is very simple and practical and can be manufactured and sold at a very nominal cost.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the mg a part of tion resides in accompanying drawing formthis application. The 1nve11- the construction, combinatlon and arrangement of parts as claimed.

In the accompanying drawing the various parts will be therein Figure 1 1s referred to by numbers, and

a top view.

Figure 2 is a side view, partly sectioned. The device forming the sub ect matter of this invention pipe leading f the steam pipe comprises a reservoir 1, which steam pipe 2 with U bolts, a pipe leading from feed glass 5. 6 is a rom the sight feed glass 5 to 2, terminating about the center thereof, the opening of the pipe 6 being toward the point of The end of the steam consumption. pipe 6 in the steam pipe 2 is cut in a slanting position, as illustrated at 7. 8 is an ad ust1ng valve. 9 1s a drain cook.

reservoir 1. 17 is a valve seat 18 on the 0011 spring arranged on 20 is a valve housing.

The device operates in the following man ner The reser voir 1 is filled with oil. The

one end valve 10 is opened. The steam passing through the steam pipe 2 creates a suction in the pipe 6, which opens the valve 14 therein. When the valve 8 is opened the oil is sucked out of the reservoir 1 through the pipes 4 and 6 into the steam pipe 2 where the steam carries it to the engine cylinder. The flow of oil may be regulated with the valve 8 as it passes through the sight feed glass 5. The valve 17 is for the purpose of relieving the vacuum in the reservoir 1 as the oil passes therefrom into the steam pipe 2. It will be noted that as the speed of the engine increases or decreases the suction in the pipe 6 will increase and decrease accordingly, which will regulate the quantity of oil used.

IVhile it is believed from the foregoing description the nature and advantages of the invention will be readily apparent, We desire to have it understood that we do not limit ourselves to what is herein shown and described, and that such changes may be resorted to, when desired, as fall within the scope of what is herein claimed.

lVhat we claim is:

1. In a steam engine lubricator, an oil reservoir, a steam pipe, a pipe connected at to the reservoir adjacent its bottom and having its opposite end arranged in the steam pipe and being open and facing in the direction in which the steam travels in the steam pipe, so as to lift the oil into the steam pipe by suction, and means above the oil level for breaking the vacuum created within the reservoir by the egressing oil.

2. A steam engine lubricator as defined in claim 1, in which the pipe extending from said reservoir to said steam pipe, has a sight flow glass disposed intermediate its ends.

3. A steam engine lubricator as defined in claim 1, in which the pipe extending from the said reservoir to the steam pipe, has an automatic valve therein disposed so as to prevent steam from causing a back pressure into said reservoir.
